2 key examples of junk science in forensics and criminal justice

ProPublica is a non-profit newsroom that investigates abuses of power. Sign up to receive our biggest stories as soon as they’re published. Decades have passed since the intersection of forensic science and criminal justice first became a pop culture phenomenon, popularized in countless TV shows, movies and books. But the growing public awareness of forensic techniques obscures a far more complex field that is rife with fake science—and the people who champion it, often for profit. For years, ProPublica has reported on these dubious techniques that have crept into every corner of our actual criminal justice system. So what isRead News

What is the key to happiness? We look at the science behind it.

Is there a key to happiness? It’s one of humanity’s greatest questions, and one we still don’t fully know the answer to. Although scientists are getting closer to identifying certain factors that can increase happiness, there are several reasons why finding a universal formula is not easy. Happiness is a complex phenomenon that is difficult to objectively define and measure. Sam Jahara, a psychotherapist at Psychotherapy in Brighton and Hove, UK (opens in a new tab), told Live Science that happiness is usually associated with joy, lightness, and gratitude. Happy people often have a positive outlook on their lives, pastRead News

Can science answer life’s biggest questions?

Dr. Alan Lightman has been around the block a couple of times. For the past fifty years, he has been a theoretical physicist, a professor at MIT, and a bestselling author, often simultaneously. His major novel, ‘Einstein’s Dreams’ has been adapted into dozens of plays and musicals since its publication in 1992, becoming one of the most famous examples of the fusion of art and science. Lightman’s work follows a philosophical way of thinking about life’s bigger questions, such as the origins of consciousness. His new venture brings that way of thinking to the big screen. “Search: Our Search forRead News

New data shows how fast light pollution is obscuring the night sky

The night sky has been clearing up faster than researchers thought, thanks to the use of artificial lights at night. A study of more than 50,000 star observations by citizen scientists reveals that the night sky got about 10% brighter, on average, every year from 2011 to 2022. In other words, a baby born in a region where about 250 stars were visible every night would only see 100 stars on his 18th birthday, researchers report in the Jan. 20 journal Science.

Science will never make philosophy or religion obsolete

For hundreds of thousands of years — all of human history — we have not had definitive answers to some of the biggest existential questions we could have formulated. How did humans originate on planet Earth? What are we made of, at a basic level? How big is the Universe, and what is its origin? For several generations, they were questions for theologians, philosophers and poets. But in the last hundred years, humanity has discovered the most compelling and plausible answers to these questions and many others that we have ever had. Through the process of experimenting and making observations, we have greatly increasedRead News

Splitting the atomic scientists: how the war in Ukraine ruined physics

In normal times, the four major physics experiments using proton collisions at Cern’s Large Hadron Collider (LHC) in Switzerland publish dozens of scientific articles a year. But in March 2022, the number of new research papers produced by the LHC experiments dropped to zero. Reason: lack of agreement on how to list Russian and Belarusian scientists and institutions, if at all. The interim agreement, which is in place so far, should not be announced. Articles are the hard currency of research, used for the exchange of information and evidence of the contributions of individuals and financial institutions. The four largestRead News

If you measure by the sheer amount of published papers, we are in the golden age of science. There are more scientists than ever; there are more publications than ever; and while much great work remains underfunded, there is more funding than ever before. Federal R&D funding has grown from $3.5 billion in 1955 to $137.8 billion in 2020, a more than tenfold increase even after adjusting for inflation. Fields like artificial intelligence and biotechnology seem to be booming, but outside of a few specific areas, like artificial intelligence and biotechnology, it doesn’t seem like we’re in a golden ageRead News

Exxon’s Own Science Was Frighteningly Accurate About Global Warming, So It Covered It Up

Despite sowing uncertainty about the existence and cause of global climate change, Exxon has privately projected global warming with frightening accuracy for decades, a new study shows. By digitizing and analyzing internal documents produced by ExxonMobil scientists between 1977 and 2002, a team of researchers from Harvard and the University of Potsdam put numbers behind recent rallying cries and hashtags that “Exxon knew” that burning fossil fuels would contribute to an increase in the global average temperature. “Our findings show that ExxonMobil didn’t just know ‘something’ about global warming decades ago—they knew as much as academic and public scientists knew,”Read News

Chocolate coats the tongue to give a melt-in-the-mouth sensation, study finds

According to scientists, chocolate’s irresistible melt-in-your-mouth sensation comes down to the way it coats the tongue. The study investigated the physical process by which a solid square of chocolate turns into a smooth emulsion. It turned out that the chocolate released a layer of fat that coats the tongue, giving a smooth feeling the entire time it’s in your mouth. Dr Siavash Soltanahmadi, lead researcher on the study from the University of Leeds, said the findings could be used to design low-fat chocolate that mimics the feel of a high-fat product. “We believe we can develop the next generation ofRead News

How India’s caste system limits diversity in science – in six charts

In recent years, groups of activists, students and researchers have been pushing institutions not only to follow quotas, but also to better support researchers from poor communities. “We’re doing this to hold up a mirror to these institutes to show how ugly they are,” says a spokesman for Egalitarians, an organization that tries to collect and publish data on diversity. The issue is part of a wider recognition of how privileged caste groups discriminate against marginalized communities – encouraged by India’s pro-Hindu Prime Minister Narendra Modi, say some academics who spoke to Nature but did not want to be named.Read News

Scientists just invented a whole new way to cool things

Say hello to ionocaloric cooling: a new way to lower mercury that has the potential to replace existing methods with something safer and friendlier to the planet. Conventional refrigeration systems transfer heat from space by cooling gas as it expands. Although this process works, some of the special gases we use are also not friendly to the environment. However, there are more than one way in which an object can be forced to absorb and release heat energy. A new method developed by researchers at the Lawrence Berkeley National Laboratory and the University of California, Berkeley, US takes advantage ofRead News

We Finally Know How Ancient Roman Concrete Was So Durable

The dome of the Pantheon. (Ed Freeman/Stone/Getty Images) The ancient Romans were masters of building and engineering, perhaps most famously represented by aqueducts. And those marvels that are still functional rely on a unique construction material: pozzolanic concrete, a spectacularly durable concrete that gave Roman structures their incredible strength. Even today, one of their structures – the infamous Pantheon, still intact and almost 2,000 years old – holds the record for the world’s largest unreinforced concrete dome. The properties of this concrete have generally been attributed to its ingredients: pozzolana, a mixture of volcanic ash – named after the ItalianRead News

The natives may have created the ‘dark soil’ of the Amazon on purpose

CHICAGO — For thousands of years, indigenous peoples of the Amazon may have intentionally created fertile soil for farming. At archaeological sites in the Amazon basin, mysterious patches of unusually fertile soil dot the landscape. Scientists have long debated the origin of this “dark earth,” which is darker and more carbon-rich than the surrounding soil. Now researchers have shown that the indigenous Kuikuro people of southeastern Brazil deliberately create similar soil around their villages. The finding, presented at the December 16 meeting of the American Geophysical Union, adds evidence to the idea that ancient Amazonians also intentionally prepared such soil.Read News
